Gate Valves are called "full-flow" valves; there's a direct unobstructed path for flow right through the middle of the valve. A wedge-shaped brass gate is lowered into a machined slot to close the valve. They should either be completely open or completely closed. Water flowing through a partially open gate valve wears away the metal and causes the valve to fail over time.

Informatization refers to the historical process of cultivating and developing new productive forces represented by computer-based intelligent tools and making them beneficial to society. (Intelligent tools, also known as information-based production tools. It generally must have the functions of information acquisition, information transmission, information processing, information regeneration, and information utilization.) The productivity that is compatible with intelligent tools is called information productivity. Intelligent production tools are different from the production tools in the past. It is not an isolated and scattered thing, but a large-scale, top-down, organized information network system. This kind of network production tool will change people's production methods, working methods, learning methods, communication methods, lifestyles, ways of thinking, etc., which will make profound changes in human society.
Informatization is a technology that combines the elements of the research object into a database based on modern communication, network, and database technologies, and combines various behaviors related to human life, work, learning, and decision-making. After using this technology, it can greatly improve the efficiency of various behaviors and provide great technical support for the advancement of human society.
Based on the introduction and summarization of many technologies for enterprise manufacturing information systems, this report proposes three types of platforms: heterogeneous information integration--interconnected information platform, support for collaborative design, simulation and optimization--interconnection Interoperable information platform, enterprise's global (integrated) optimization operation - modeling and optimization platform. These three types of information platforms are the process from "integration" to "coordination" and "optimization" since the beginning of the 863 program, and also the development process of manufacturing informationization in the world.
I. Enterprise Manufacturing Information System
Although different expressions will appear according to different companies, they should be classified according to the basics, including: OA (Office Automation), PLM (product lifecycle management), CAE (Computer Aided Engineering). (Computer Aided Engineering), CAD (Computer Aided Design, VM (Supplier Management), PDM (Product Data Management, Engineering DB (Database), ERP (Enterprise Resource Planning) That is, (Enterprise Resource Planning), management database, MES (manufacturing execution system), and PLC (Programmable Logic Controller) and the like.
Second, heterogeneous information integration---interconnected information platform
For discrete manufacturing, information integration of design process CAD, CAPP, CAM, CAE, PDM (product data management) can be used as a platform tool. If it is the CAX software of the same manufacturer, it is easier to implement information integration with STEP (Product Data Exchange Standard). If it is a CAX software from different vendors, information integration has to do a little work because it is a subset of STEP. This kind of information integration has a large number of R&D work including a certain level, such as virtual assembly, virtual manufacturing, and concurrent engineering based on information integration. Regardless of military or civilian use, it is almost 100% effective.
If MES is added, the digital workshop can be realized, and the product design process and manufacturing process can be integrated. Then it must be to achieve integration with ERP. 
If you want to integrate information integration between design process and management, you should also have a coding system (covering products, components, raw materials, etc. inside and outside the enterprise supply chain) and a BOM (contact design and management). On this basis, PLM The platform can meet this need. The problem is that China's PDM and PLM are mainly small software, and large-scale such tools are the shortcomings of China. 
For the process industry, its information integration is mainly the exchange of information between heterogeneous databases. Process control requires a real-time database to store information such as sensing, status, control, and execution of the site. MES, especially ERP (using a relational database) does not require such high frequency sampling. This conversion of data (including integration of course) should be provided by the corresponding DCS manufacturer.
Third, collaborative design, simulation and optimization---interaction and interoperability information platform 
Fourth, the conclusion
1. In the next 20 years, information technology will be widely and more deeply influenced by the world. Lead to social progress, economic development, and a higher quality of life. Today's big data, cloud computing, mobile Internet, etc. all illustrate the guiding and driving role of information technology, and integration, collaboration and optimization are still the in-depth needs of these popular technologies.
2. The three types of information platforms mentioned are a step-by-step process of “integration†since the beginning of the 863 Program. Both are useful and can be level. What is important is “industrialized demand orientation, enterprise demand orientation, and enterprise benefit orientation.â€
3. No matter which type of platform its depth depends on the depth of scientific intersection: computer knowledge and innovation in the intersection of many fields of knowledge, one of the core issues is the "system": system model, optimization and implementation.

"Advanced Manufacturing" is an interdisciplinary subject. From the perspective of information technology, it focuses on the application of various computer-aided technologies in manufacturing. Another important aspect is information integration: interconnection and interoperability, which is an inevitable demand for advanced manufacturing development. . From the perspective of system theory and technology, more attention is paid to advanced manufacturing as a system. The core issue is modeling and optimization.
